# ChatJS
Stop rebuilding the same AI chat infrastructure. ChatJS gives you a production-ready foundation with authentication, 120+ models, streaming, and tools so you can focus on what makes your app unique.
[**Website**](https://chatjs.dev) · [**Live Demo**](https://demo.chatjs.dev) · [**Documentation**](https://chatjs.dev/docs)
## CLI
Create a new ChatJS app:
```bash
npx @chat-js/cli@latest create my-app
```
The CLI walks you through gateway, features, and auth choices, generates `chat.config.ts`, and lists the env vars required by your selections.
## Features
- **120+ Models**: Claude, GPT, Gemini, Grok via one API
- **Auth**: GitHub, Google, anonymous. Ready to go.
- **Attachments**: Images, PDFs, docs. Drag and drop.
- **Resumable Streams**: Continue generation after page refresh
- **Branching**: Fork conversations, explore alternatives
- **Sharing**: Share conversations with public links
- **Web Search**: Real-time web search integration
- **Image Generation**: AI-powered image creation
- **Code Execution**: Run code snippets in sandbox
- **MCP**: Model Context Protocol support
- **Desktop App**: Package as a native macOS, Windows, or Linux app with Electron
